For the most part: true!

But I also replaced the motherboard (I had an identical spare) which 
involved re-seating the CPU, and re-thermal-pasting
Also I recorded the thermals, it was all nominal.

The big problem is I was tired of dicking-around with it, and wanted it to 
Just Work (TM).  Now it does :D

You don't realise how much you depend on MythTV working.
Ok so the kids wont go hungry if it doesn't perform, but it makes life just 
that little bit nicer.

thanks for the suggestions,
